The incidence of pancreatic cancer is gradually increasing worldwide. The overall 5-year survival rate of pancreatic cancer is about 5%, because the early diagnosis is difficult and the radical resection rate is low in pancreatic cancer. The keys of improving the poor prognosis of pancreatic cancer are early diagnosis and radical resection. Detection of serum tumor markers has an important utility in the diagnosis, prognosis and surveillance of pancreatic cancer. CA19-9 is the most widely used and best validated serum tumor marker for pancreatic cancer although it has some limits. With the development of molecular biological techniques in recent years, several potential serum tumor markers for pancreatic cancer are undergoing evaltation, including MIC- 1, M2- PK, OPN, RCAS1, and so on. This paper is to review the current status of serum tumor markers of pancreatic cancer.

Objective To investigate the effect of tetrandrine (Tet) on experimental choroidal neovascularization and the effect of Tet on retinal structure and function. Methods Choroidal neovascularization was induced in 20 Brown Norway (BN) rats (40 eyes) by diode laser (wavelength: 810 nm; exposal time: 0.1 second; facular diameter:100 ?m; energy: 120 mW), and the rats were divided randomly into experimental and control group with 10 rats (20 eyes) in each group. In experimental group, 0.05 ml Tet with the concentration of 3.21 ?mol/L was injected intravitreously 0 and 3 days after laser photocoagulation; in the control group, the rats underwent an intravitreous injection with the same volume of sodium chloride solution. The incidence of CNV was evaluated by fundus fluorescein angiography (FFA) 14 days after laser photocoagulation. Five right eyes of another Five healthy BN rats underwent intravitreous injection with 0.05 ml Tet with the concentration of 3.21 ?mol/L, and an intravitreous injection with the same volume of sodium chloride solution was performed on the left eyes. Before injection, 1 hour, and 1 day after the first injection, and 1 hour, 1 day, 7 days, 14 days after the second injection the electroretinography (ERG) was performed on these 5 rats; 14 days after the second injection, the retinae were examined by light microscopy and transmission electron microscopy. Results The incidence of CNV was 23.26% in experimental group,which was obviously lower than that in the control group (63.33%) (P0.05). There were no structural changes of retinal tissues examined by light and electron microscopy. Conclusion Tet may inhibit choroidal neovascularization in rats; there isn′t any significant toxic effect of intravitreous injection with Tet on retina at the dosage of 3.21 ?mol/L.

Therapeutic approaches to brain metastases from non-small cell lung cancer ( NSCLC ) include corticosteroids, anticonvulsants, surgery, radiotherapy and chemotherapy. In recent years, molecular targeted therapy such as the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) has become a new option. This article discussed the roles of surgery, brain radiation, chemotherapy, targeted therapy , and other new directions in the treatment of patients with brain metastases from NSCLC.

Objective To observe the effects of turicamycin-inhibitor of N-glycosylation of proteins on expression of (?1 integrin,FAK and cyclin D1 in high glucose-induced glomerular mesangial cells (CMC), and to explore the mechanism concerned. Methods Cultured HBZY-1 rat mesangial cells were divided into 5 groups:control group;high glucose group;mannitol group;high glucose plus TM group; TM group.The expression of ?1 integrin was measured by flow cytometry, expression of FAK and cyclin D1 was measured by immunohistochemistry,and proliferation of GMCs was measured by MTT. Results There was a little expression of ?1 integrin, FAK and cyclin D1 on normal mesangial cells. High glucose induced the proliferation and increased the expression of ?1 integrin and cyclin D1.There was no significant difference in mannitol group as compared to control group.The expression of (?1 integrin FAK and cyclin D1 decreased notably by TM.TM could also decrease proliferative abilitiy of cells. All the effects of TM were dose-dependent. Conclusion Through blocking glycosylation of glycoprotein, TM can suppress cellular proliferation and expression of pi integrin induced by high glucose in a dose-dependent manners,then pi integrin affects the expression of FAK and cyclin D1.
